Indigo is among the oldest dyes to be used for textile dyeing and printing. Many Asian countries, such as India & Japan have used indigo as a dye for centuries, however they used differing plant species to produce the dye. Dyer's Knotweed, as this variety is known, is a tropical heat loving plant which is why we gave it a try at our urban farm, which is in Plant Hardiness Zone 10b.Our experimental indigo patch flourished last fall, producing two flushes of harvestable green growth and then proliferated an abundance of viable seed. Once established in your garden your Japanese Indigo plants can also be propagated easily from cuttings. We suggest gardeners growing Indigo in the tropics plant in Fall or winter. While using fresh indigo leaves for its famous dark blue hues does involve some advanced technique and processing fresh leaves can be used to create subtle tons of aqua, teal and green, depending on the fabric, mordant & water used. If your indigo starts making beautiful long seed flushes while it’s still young just prune them off to encourage it to make more leaves instead.
